Introduction
A particle counter is an instrument used to measure the number and size distribution of particles in air, liquids, or gases, and it is used for cleanliness monitoring, contamination control, and quality assurance in cleanrooms, industrial processes, and laboratories. Particle counters operate on various principles, including light scattering, in which particles passing through a light beam scatter light that is detected and counted, with the intensity of the scattered light related to the particle size; light obscuration, in which particles block a portion of a light beam, causing a reduction in detected light; and condensation particle counting, in which ultrafine particles are grown to detectable size by condensing vapor onto them, and the instrument reports particle counts in various size channels, such as 0.3, 0.5, 1.0, and 5.0 micrometers. Airborne particle counters are used in cleanrooms and pharmaceutical, semiconductor, and biotechnology facilities for monitoring airborne particle cleanliness according to standards such as ISO 14644; in HVAC and indoor air quality monitoring; in hospitals and laboratories for contamination control; and in industrial processes for quality control, and liquid particle counters are used for monitoring contamination in liquids, such as water, chemicals, and pharmaceutical solutions. They are available as portable handheld instruments, benchtop units, and online monitors with continuous sampling and alarm functions, with features such as multiple size channels, data logging, and software. With their importance in contamination monitoring, particle counters are essential instruments for cleanroom and process control.

FAQ
Q1: What testing scenarios is this counter mainly applied to?
A: The particle counter is used in cleanroom monitoring, pharmaceutical manufacturing, electronics production, food processing, aerospace, environmental monitoring and indoor air quality assessment to measure the concentration and size distribution of airborne particles. It supports cleanroom certification and monitoring per ISO 14644, pharmaceutical manufacturing environmental monitoring, electronics and semiconductor cleanroom control, food processing facility monitoring, indoor air quality assessment, HVAC system performance testing, and containment verification. The optical particle counter provides real-time measurement of particle counts at multiple size ranges, enabling assessment of air cleanliness and contamination control. It is essential for pharmaceutical, electronics, food and aerospace manufacturers, cleanroom operators, environmental consultants and facility managers requiring airborne particle measurement for cleanroom certification, regulatory compliance, contamination control, indoor air quality assessment and HVAC performance, where particle concentration is a critical indicator of air cleanliness, filtration efficiency, contamination risk and environmental control in regulated manufacturing, healthcare and research environments.
Q2: What standards does the counter comply with?
A: The particle counter follows ISO 21501-4 for particle counter calibration, ISO 14644 for cleanroom classification, relevant GMP requirements for pharmaceutical manufacturing, and applicable GB/T standards. Calibration should be performed by an accredited laboratory using traceable aerosol standards. The instrument complies with relevant safety standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole particle counter is covered by a 12-month warranty. The optical sensor, pump, electronics and display are covered, while filters, tubing and batteries are consumables or accessories. Damage from improper use, exposure beyond sensor range or unauthorized repair is excluded. Extended service contracts are available for cleanroom monitoring equipment.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained personnel familiar with cleanroom monitoring, particle counting principles and data interpretation. We provide operation manuals, training and application support. Proper sampling technique, location selection, calibration verification and data interpretation are important for valid particle measurement, particularly for regulated cleanroom certification.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration by an accredited laboratory recommended annually or per ISO 21501-4 requirements. Routine verification with a reference before critical cleanroom certification. Pump flow rate calibration periodically. Filter replacement per schedule. Sensor condition checked per manufacturer recommendation. Full maintenance and calibration service recommended for regulated use.
Q7: Are supporting consumables universal?
A: Filters, tubing and batteries are available from specialized suppliers, though instrument-specific parts should be verified. Long-term consumable and calibration cost is moderate, with annual calibration being a key recurring expense.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes size channels, flow rate, portability, data logging, communication and monitoring system integration. Additional probes, tubing and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the particle counter and accessories with an operation manual. On-site installation, calibration and training are not included for standard portable orders but can be arranged for fixed monitoring systems. Remote guidance is provided.
Q10: What types of environments are compatible with this equipment?
A: The particle counter measures airborne particles in cleanrooms, manufacturing areas, laboratories and indoor environments within the concentration range and size specification. Highly concentrated particle environments may exceed the counting range and cause coincidence errors. Corrosive or explosive atmospheres require special-rated instruments. Users should follow proper sampling procedures per ISO 14644 including sample volume, location and number of points, calibrate the instrument regularly by an accredited laboratory, allow proper purge time before sampling, avoid sampling in high-concentration areas beyond the range, maintain pump and filter, and report results with complete sampling parameters for cleanroom certification. For regulated pharmaceutical use, procedures should follow GMP and applicable regulatory requirements.
